PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 684,223, dated October8, 1901.

Application filed March 5,- 1901.

To all whom it may concern.-

Be it known that I, E WARD FRANKLIN GRANDY, of Dorchester, Boston, inthe county of Suffolk and State of Massachusetts, have invented certainnew and useful Improvements in Printing-Presses, of which the followingis a specification.

This invention has relation to multicolor cylinder-presses of the typeillustrated in the patent to HenryE. Grandy, No. 484,421, dated October18, 1892. Such presses included a form=cylinder having a plurality ofprintingplates in its periphery, with each of which were adapted tocoact a series of form-inking rolls. Each series of rolls was adapted toreceive and transfer ink of a particular color to a predetermined plate,mechanism having been provided for automatically bringing the ink-rollsinto contact with the plate on the cylinder at the proper time. Theform-inking rolls and the distributing-rolls occupied a fixed relationto each other and were bodily movable by a cam mechanism toward and fromthe periphery of the form-cylinder.

The object of the present invention is to provide certain improvementsin the press thus briefly described-first, in the ink-rolls and themechanism for moving them by means of which the distributing-rolls canoccupy a fixed relation to the form-cylinder, and thus relieve the cammechanism from the great weight hitherto borne by it, and thereby reducethe power necessary to operate the distributing-rolls, and, second, toimprove the cam mechanism itself,whereby the movement of the ink-rollsmay be accomplished evenly and smoothly and without jarring.

On the accompanying drawings, forming a part of this specification,Figure 1 represents a portion of a printing-press embodying myimprovements. Fig. 2 represents an enlarged view of the form-inkingrolls and the distributing-rolls which coact therewith. Fig. 3represents a longitudinal section on the line 3 3 of Fig. 2. Fig. 4represents a section 011 the line 4 4 of Fig. 2. Figs. 5 and 6 representin detail one of the adjusting devices for one of the form-inking rolls.

Referring to the drawings, 20 indicates a suitable frame, in which arejournaled trunnions 221 of the form-cylinder 21. This cylinder isprovided for the reception of a plu- Serial No. 49,939. a. model.)

copy the same segment of a circle that the corresponding printing-plateoccupies. These cams are provided with inclined ends, (not shown,) andthey are arranged at different radial distances from the axis of thecy1in der. Motion is imparted to the cylinder in the usual manner.Mounted upon the frame are a plurality of series of inking-rolls, therebeing one series for each printing plate or cam 57, each series ofprinting-rolls being controlled by a certain cam and being unaffected bythe other cams.

The form-rolls are indicated at 27 27, and they are arranged incontiguity with the distributing-rolls 22 22, the latter occupying afixed position with relation to the axis of the form-cylinder.

The distributing-rolls receive their motion from the form-cylinder, thelatter being provided with gear-teeth intermeshing with and drivingidler-gears 100, which in turn int-ermesh with gears on the shaft of thedistributing-rolls.

' Hitherto, as has been explained, it has been the custom to move thedistributing-rolls to ward and from the cylinder, so that it wasnecessary to form the gears with relatively long teeth to permit ofrelative movement. By mounting the distributing-rolls, however,

on stationary bearings it is unnecessary to change the relationship ofthe gears, whereby the noise caused by operating the cylinder is greatlyreduced according to the present invention.

The form-rolls 27 27 are, as stated, in contiguity with thedistributing-rolls, and they are automatically moved toward and from theperiphery of the cylinder, so as to engage and ink the printing-platesthereon, said rolls swinging in the arc of a circle about the axes ofthe distributing-rolls. Y

Each roll 22, as shown in Figs. 2, 3, and 4, is fixed on a shaft 23,which carries the gears 101, intermeshing with the gears 100. The shaft23 is journaled at each endina block 24 in a bracket 25, secured rigidlyto and projecting outward from the frame 20. Between the block 24 andthe bracket 25 there is interposed a sleeve 28, which is held againstrotation by a set-screw 29 passing through the bracket into firmengagement therewith.

The bearings for the rolls 27 are upon the ends of arms which arefulcrumed upon the said sleeves 28. The shaftupon which each roll 27 isjournaled is indicated at 30. It is mounted at each end in asleeve-bearing 31,. which is provided with an elongated transversedovetail groove 32 to receive a complemental tongue 33 upon a bar 34.This bar is arranged in parallelism to the shafts and 23, and it isprovided with two eyes or straps 3 5 36, which encircle the sleeve 28.The

tongue 33 is elongated, as shown in Fig.5,

. and it is formed with a groove 38 to receive a lug 39 from the sleeve31. v

Arranged in the groove 38 there is a screw 40, having similar endsproperly journaled in the stock at the end of the groove 38, as shown inFig. 5, said screw passing through a thread ed aperture in the lug 39.One end of the screw is provided with a collar 41, affixed thereto,while at the other end of the screw there is a head of wrench-retainingformation by which the screw may be rotated to adjust the sleeve orhearing 31. Thus adjustment for the sleeve 31 is providedrwhereby theroll 27 may be kept properly in contact with the distributing rolls 22.The bar 34 has an elongated dovetail tongue 43 arranged transverselythereto and projecting radially relatively to the cylinder. This tongueis grooved, and in the groove lies a screw 44, similar to that at 40.The screw is engaged with the lug of a grooved block 45, (see Fig.

3,) so that said block may be adjusted radially of the cylinder and on aline transverse to the line of adjustment of the sleeve-bearing 31.

The block 45 at each end of the press is connected by a link 46 with apin 47, which into and out of engagement with the cylin der 21. The link46 has a loose or pivotal connection with the block 45 through themedium of a pivoted pin 54, and it is likewise pivotally connected tothe pin 47, being held between a flange and a nut 56 thereon. In orderto move the slide inward against the pressure of the spring 51, I employmechanism actuated by the face-cams57 on the ends of the cylinder 21.

In Fig. 3 one of the earns 57 is illustrated in section, and it is shownas bearing against a roll 58, journaled in the end of a Wedge 59, whichpasses through the frame 20, being guide 50.

when the wedges are forcedoutward orin the. 85

either angular or provided with means to r 1 P hold it against rotation.The end of theg wedge projects into a socket provided by V hollowbracket or casting 60, secured to the 70} i This hollow bracket isreadily'ref; movable, being secured in place by screws 1.

or belts in any desired way. The rolls 58 are each held yieldinglyagainst the cams 57 or r g i. the ends of the cylinder by a spring .61,arranged in a socket and having one end bear- 7 :5 ing against the wedge50 and its other end resting against a disk 62, which is adj ustable bymeans of a set-screw 63 to varythe ten-. sion of the spring. The wedgepasses through 89 an aperture or slot 64 in the slide '49, and it isprovided with an incline 65, against which" the roll 66 is heldyieldingly by a spring 51. From this descriptionit will be observedthat".

direction of the arrow in .Fig. 3 the inclines-1 65, hearing against theroll 66, will forcethe slides 49 inwardly and move theroll 27 into;engagement with the form-cylinder without 1 affecting its contiguit-ywith the roll 42; The connections interposed between the: slide 45andthe roll 27 are, as has been shown, readily adjustable to compensateforthe; wear on the roll 27 or the transferring-roll.2 2, whereby theform-roll 27 may be adjusted HI-" ward and from the form-cylinder andalso toward and from the distributing-roll. 1The; form-rolls 27 may bearranged in pairs to op-f erate in conjunction with a single distribut?ing-roll, or there may be the single form-roll 0 for eachdistributing-roll, this being a mat ter of convenience and discretion.In addition to preparing an accurate adjust-v I ment of the form-rollsrelatively to the formcylinder and the distributing-rolls thermechr I05anism which I have provided insures a move-' W g ment of the form-rollstoward and from'op; 2 erat-ive position without jarring and with'a Ismooth easy motion. By the .employment.{ V V oi the face-cams and thewedges operated 1116' thereby the power necessary to actuate theform-roll connections is greatly reduced,when} considered in connectionwith the devices? hitherto employed for a similar purpose, and,moreover, the face-cams being on the cylinder 11$? i end take upbutlittle room. The wedges bear 7 against the faces of the cams and areattached; to the cylinder ends, and there is no danger,': 7} therefore,of loosening the cams, and thereby decreasing the accuracy andeiiiciency of the. i210" mechanism. Moreover, the mountingof the i,distributing-rolls upon fixed bearings relieves 1 7 the cam actuatedmechanism from their" 7 weight, this being of great assistance in the;reduction of the power necessary to actuate 1 25 the mechanism. r T Itis not necessary to illustrate the opera f tion of the mechanism furtherthan has been already done, save to state that each series V ofprinting-rolls is drawn-into operative rela 1 o tion to a printing-plateas the corresponding cam engages the mechanism for moving said 7 roll,and consequently each plate receives ink of its proper color. Inconnection with this mechanism I provide improved devices for moving thefeeding or paper cylinder toward and from operative position. The saidcylinder is shown in Fig. 1, to which reference may now be had. It isindicated at 80, and its trunnions are journaled in split boxes 81,supported upon springs 82 in standards 83. The standards are formed withguides, in which the boxes are adapted to reciprocate.

The springs 82 normally hold the boxes raised with the feeding or papercylinderin inoperative position. To move said cylinder, I employ wedges84., interposed between rolls 85 on the top of the standard and rolls 86on the boxes 81. The wedges are formedwith rolls or projections 87,extending into segmental slots 88 in levers 89, which are fulcru med at90. The slots 88 are eccentric with respect to the fulcrums 90, so thatthe oscillation of the lever effects a longitudinal or reciprocatorymovement of the wedges 84. The levers are connected by links 91 withlevers 92 upon the ends of a shaft 93. One of the levers 92 is connectedby two connecting-rods 95 96 with two foot-levers or treadles 97 98,respectively, which are fulcrumed at 99 upon the platform 105. Thelevers 98 97 are of the first and second classes, respectively, that at97 being depressed by the foot for swinging the levers S9 upward,whilethat at 98 is employed for swinging the said levers 89 downward. Fromthis it will be seen that by depressing the proper lever the boxes 81and the paper-feeding cylinder 80 may be raised to operative or loweredto inoperative position, as occasion may require.

The employment of the wedges for varying the position of the boxes inthe feed-cylinder reduces the power necessary to move them and providesfor the said parts being actuated with an even smooth movement. I do notherein claim, however, the above-described paper-feeding mechanism, as Ihave filed an application therefor.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, although without attempting to setforth all of the forms in which it may be made or all of the modes ofits use, I declare that what I claim is- 1. In a color-printing press, aform-cylinder adapted to carry a plurality of forms, a distributing-rollin fixed relation to said cylinder, a form-roll in contiguity to saiddistributing-roll, and automatic mechanism including cams on saidcylinder for moving said form-roll into and out of operative relationwith said cylinder without destroying its contiguity to saiddistributing-roll.
